TL;DR: In this article, the authors describe their experiences in developing and teaching an introductory course in the Department of Aerospace Engineering, University of Michigan, on performance of aircraft and spacecraft systems, with emphasis given to the way in which flight models, system concepts, control, and performance topics are introduced to undergraduate students with minimal prerequisites.
Abstract: We describe our experiences in developing and teaching an introductory course in the Department of Aerospace Engineering, University of Michigan, on performance of aircraft and spacecraft systems. The special interdisciplinary features of the course are identified, with emphasis given to the way in which flight models, system concepts, control, and performance topics are introduced in the context of aircraft and spacecraft flight to undergraduate students with minimal prerequisites. The important role of technical communication in achieving the course objectives is described.

TL;DR: In this paper, a framework for sampled data control of large space structures, in terms of discrete time recursive equations in second order form, is developed for analyzing the simplest control scheme where the loop is closed using constant gain output velocity feedback.
Abstract: A framework is developed for sampled data control of large space structures, in terms of discrete time recursive equations in second order form. This framework is used to analyze the simplest control scheme where the loop is closed using constant gain output velocity feedback. It is shown that the closed loop is stable if the feedback gain is positive definite and not too large, and if the output velocity feedback is properly specified. Properties of such a stabilizing controller establish the advantage of analog control of the form considered.

TL;DR: A 3D pendulum implemented using a triaxial air bearing system is proposed for Earth-based testing of orbiting spacecraft attitude dynamics and closed loop systems.
Abstract: A 3D pendulum implemented using a triaxial air bearing system is proposed for Earth-based testing of orbiting spacecraft attitude dynamics and closed loop systems. This proposal is based on prior research on attitude dynamics and control of orbiting spacecraft, attitude dynamics and control of the 3D pendulum, and an experimental implementation of the 3D pendulum in our laboratory, referred to as the triaxial attitude control testbed (TACT). These research themes are integrated to assess the strengths and weaknesses of such an Earth-based testbed for spacecraft attitude dynamics and control hardware and software components. Several different cases, based on the importance of orbital effects and gravitational effects, are analyzed.

TL;DR: In this paper, the authors survey three basic problems regarding stability and design of switched systems, including stability for arbitrary switching sequences, stability for certain useful classes of switching sequences and construction of stabilizing switching sequences.
Abstract: By a switched system, we mean a hybrid dynamical system consisting of a family of continuous-time subsystems and a rule that orchestrates the switching between them. The article surveys developments in three basic problems regarding stability and design of switched systems. These problems are: stability for arbitrary switching sequences, stability for certain useful classes of switching sequences, and construction of stabilizing switching sequences. We also provide motivation for studying these problems by discussing how they arise in connection with various questions of interest in control theory and applications.

TL;DR: In this paper, two major figures in adaptive control provide a wealth of material for researchers, practitioners, and students to enhance their work through the information on many new theoretical developments, and can be used by mathematical control theory specialists to adapt their research to practical needs.
Abstract: This book, written by two major figures in adaptive control, provides a wealth of material for researchers, practitioners, and students. While some researchers in adaptive control may note the absence of a particular topic, the book‘s scope represents a high-gain instrument. It can be used by designers of control systems to enhance their work through the information on many new theoretical developments, and can be used by mathematical control theory specialists to adapt their research to practical needs. The book is strongly recommended to anyone interested in adaptive control.

TL;DR: In this paper, the authors introduce the concept of hybrid systems and some of the challenges associated with the stability of such systems, including the issues of guaranteeing stability of switched stable systems and finding conditions for the existence of switched controllers for stabilizing switched unstable systems.
Abstract: This paper introduces the concept of a hybrid system and some of the challenges associated with the stability of such systems, including the issues of guaranteeing stability of switched stable systems and finding conditions for the existence of switched controllers for stabilizing switched unstable systems. In this endeavour, this paper surveys the major results in the (Lyapunov) stability of finite-dimensional hybrid systems and then discusses the stronger, more specialized results of switched linear (stable and unstable) systems. A section detailing how some of the results can be formulated as linear matrix inequalities is given. Stability analyses on the regulation of the angle of attack of an aircraft and on the PI control of a vehicle with an automatic transmission are given. Other examples are included to illustrate various results in this paper.

TL;DR: Nonholonomic control systems as discussed by the authors provide a good introduction to the subject for nonspecialists in the field, while perhaps providing specialists with a better perspective of the field as a whole.
Abstract: Provides a summary of recent developments in control of nonholonomic systems. The published literature has grown enormously during the last six years, and it is now possible to give a tutorial presentation of many of these developments. The objective of this article is to provide a unified and accessible presentation, placing the various models, problem formulations, approaches, and results into a proper context. It is hoped that this overview will provide a good introduction to the subject for nonspecialists in the field, while perhaps providing specialists with a better perspective of the field as a whole. The paper is organized as follows: introduction to nonholonomic control systems and where they arise in applications, classification of models of nonholonomic control systems, control problem formulations, motion planning results, stabilization results, and current and future research topics.
